What is backflow?

The City of Red Oak’s water system is designed to keep water flowing, from our distribution system, to you, the customer. Backflow can occur due to high pressure on the customer side, or low pressure in the City’s water system. Backflow is the undesirable reversal of water flow in a potable water system through a cross-connection. This situation may allow liquids, gases, non-potable water, and other substances, from any source, to enter a public water system.
